I bought these pistons from a member off of here for basically for basically dirt cheap in a package deal, there used SRP's. They originally came form the member Spun Vtec but he doesnt seem to remember the compression of them

They are for a D16
They are SPR forged based on the thick ringlands
They have a #10 and SRP logo stamped inside of them

Heres the measurements I took with a digital vernier



Pics a little blurry but the 4 measurements are all there

Heres an overhead pic if it helps



Now any other measurements you guys need I will gladly take as Im doing absolutely nothing this weekend, girlfriend is sick and Im just keeping company while she sleeps I guess. Ive got the used rings they were used with

Im hoping someone can help me identify what pistons they are exactly from SRP's lineup and what compression they will yield in what motors. Im going to be using them in a D16A6 with a .040 milled head, just need a compression number to see if I should sell them or not.

Thanks

how much u get them for.... to my understanding theyare 9:1 compression... i bought a set of used ones.... they have a 10 on them too ... he said 9:1... and i kow on anohter forum a guy was sellinga set of 9:1 and he had a 10 too inside

W O T

9:1 for which motor though

Maybe Ill have to get a thick Cometic gasket or raise the **** out of it even more with a 2 layer y8

Im thinking they all have a 10 stamped on the bottom though

BTW-I got them in a huge deal, my 2 1000w amps + tial 38mm wg + wideband w/ display for his SRP pistons + D16 88 tranny + turboedit chipped pm6 and 2.5" charge pipes

USDM 4G VTEC

hard to tell

remember they have diff bore sizes
wich one u got?? measure the piston for 75.00,75.25,75.50 or 76mm

they came on 9.0:1 CR and 10.5:1

platinum00

i had a set of 8.5.1 for a y8, that had a 10 stamped on them.

call JE, they should be able to tell you.

platinum.

AHHHHHHHHHHhhhhhhhhh are u serious ...oh man i didin;t kow that ... hmmm dam 10 on a 8.5..... shiza....... hey when u find out from JE tell me too hahaha

they dont have a 8's compression pistons for the Y8 or Z6's

i called for my engine built up and ended up getting the 9.0:1

they make one for the A6, but i wouldnt mix match them

I can't answer the question but I hope there aren't any scuffs on the side of the pistons

Theres some veritcal microscratching on the skirts, cant feel it but you can see it a bit

Anyways, Im stumped

Thanks for the link though

If you can measure the compression height, that will help you nail it down more quickly.



Those pistons are dished, so if you know the comp height and that they are dished, that will narrow it down a lot.

yea they only make the 8.5.1's for the A6, i used these in my Y8 with no problems. now i think since the heads are different the real compressoin may have been closer to ~9.1

platinum.

soon as Im home Ill throw you a compression height number, doesnt look to hard

Want it in mm or inches?

W O T

1.1706inches

30mm

I think I got it near perfect

It doesn't look like SRP makes a piston with that compression height. Compression height is really hard to measure accurately.

That piston in the pictured (on the Flatlander site) looks like a -11cc dish.

well on that site they have 1.161 listed.....

I guess my margin of error would be my pen width which would possibly make up for the 10 thousands difference

This is killing me, I wanna assemble and install this motor

Also, the piston thats pictured on the link isnt what I have, the inner section drop on that one looks huge

if u use those srp pistons, je doesnt recommend u to go over 16psi with them. i ran 20psi and they fell apart. i can post so pics tomorrow.

That doesn't really seem like much of a deal...?

To each they're own I guess.
